Covariate-specific receiver operating characteristic (ROC) curves are often used to evaluate the classification accuracy of a medical diagnostic test or a biomarker, when the accuracy of the test is associated with certain covariates. In many large-scale screening tests, the gold standard is subject to missingness due to high cost or harmfulness to the patient. In this article, we propose a sem...

Starting from the residual estimates for GMRES formulated by many authors, usually in terms of the quotient of the Hermitian part and the norm of a matrix or by using the field of values of a matrix, we present more general estimates which hold also for restarted and augmented GMRES. Sufficient conditions for convergence are formulated. All estimates are independent on the choice of an initial ...

This study aims to solve the most general form of linear mixed Volterra-Fredholm integro-differential equations multi-fractional order in Caputo sense (MV-FIFDEs), which is solved by using orthogonal generalized Bernstein’s polynomial expansion with collocation and moment discrete weighted residual method under suitable conditions; then, Clenshaw-Curtis formula applied approximate integral term...

Residual stresses have become an important player in the field of the structural integrity for many years. Having an exact knowledge of residual stress distributions can be essential in designing the engineering components as unexpected failures are inevitable where such stresses are ignored.  There are many residual stresses measurement techniques including destructive and non-destructive ones...

BACKGROUND AND PURPOSE In clinical studies, evaluating residual fiber tracts in spinal cord injuries poses serious difficulties, whereas diffusion tensor imaging (DTI) can assess alterations in fiber structural integrity. For this reason, this study aimed to determine changes in the structural integrity of residual fiber tracts via fractional anisotropy (FA) variations and fiber-tracking patter...

We consider the solution of complex symmetric shifted linear systems. Such systems arise in largescale electronic structure simulations, and there is a strong need of algorithms for their fast solution. With the aim of solving the systems efficiently, we consider a special case of the QMR method for non-Hermitian shifted linear systems and propose its weighted quasi-minimal residual approach. A...

A software fingerprint is a set of distinctive characteristics used to identify and compare programs. This paper presents a fingerprint technique based on the characteristics of method signatures. The proposed technique considers uncommon method signatures as being more effective than common ones to compare programs. The implementation of this technique is limited to Java programs, but it could...

Issues relating to routing algorithms are important in mobile ad hoc network (MANET) research. In this paper, we present an adaptive weighted routing algorithm that exhibits low cost and high efficiency. In our method, important factors including hop count, end-to-end delays, and node residual energy are considered. The proposed routing algorithm dynamically adjusts the parameters of the routin...
